WebFeb 2, 2009 · Beta is not used for a saturated transistor. The collector to emitter voltage for the beta spec is much higher than it is for a saturated transistor. The minimum beta for a 2N3904 transistor at 1ma and with a vce of 1.0V is 70. But its max saturation voltage of 0.2V is when its base voltage is much higher than 1/70th, it is 1/10th.

WebSep 5, 2008 · 59,588. bjt hfe. HFE is beta. It changes with each transistor even if they have the same part number because it is a range. Some transistors have a high beta and others have a low beta. See the range on the datasheet for a transistor. Beta is the current gain, not the voltage gain of a transistor. Beta is affected by the amount of current and ... WebJun 13, 2011 · 8,353. May 13, 2011. #5. Way back when I took transistor theory our book was "Wave generation and shaping" by Leonard Strauss, and our professor (who by a curious coincidence was also named Leonard Strauss) taught us to just assume the beta of a transistor was 30 minimum, as that was the criteria for an IC wafer acceptance. WebThe beta (β) of a transistor, or transistor current gain, is the ratio of the transistor’s collector current (Ic) to its base current (Ib), as shown in Equation 1. β = Ic/Ib (1) The β value is fixed for a given transistor and operating condition.
